Know how I know this is fake?
1) The characters mentioned are from the casting call
2) Multiplayer has already been partially revealed and does include XP
3) Taking Drugs is a feature Rockstar have never put into their final games but is always on these fanwank lists
4) Same goes for Speeding, Rockstar have never included that as it tips the fun balance out to more annoying measures, but again, is always something that appears in these lists
I'm actually surprised we didn't also see the usual "Vehicles will have Gas that drains and needs to be refueled" one that's appeared on every rumour list since Vice City!
